Impact of Plant Nutrition on Pratylenchus penetrans Infection of Prunus avium Rootstocks.
A hypothesis that cherry rootstocks grown under optimal nutrient conditions are affected less by Pratylenchus penetrans infection than those grown under deficient nutrient conditions was tested by growing four Prunus avium L. rootstocks ('Mazzard', 'Mahaleb', 'GI148-1', and 'GI148-8') at a soil pH of 7.0 over a period of 3 months under greenhouse conditions (25 ñ 2 degrees C). Pratylenchus pene...
متن کاملPratylenchus penetrans Population Dynamics on Three Potato Cultivars.
Reproduction of Pratylenchus penetrans on the potato cultivars Hudson, Katahdin, and Superior was determined in greenhouse and field microplot experiments. Although all three cultivars were good hosts for P. penetrans, differences in reproductive rate were found. In one greenhouse experiment, Katahdin plants inoculated with 1,500 or 15,000 P. penetrans per pot had larger population densities at...
متن کاملAnhydrobiosis in Pratylenchus penetrans.
Anhydrobiotic survival of Pratylenchus penetrans was compared in several soil moisture regimes. Bodies of anhydrobiotic nematodes were coiled. In slow-dried soils, Vineland silt loam (VSL) and Fox loamy sand (FLS), 70 and 58% of the total P. penetrans populations were anhydrobiotic when soil moistures reached ca. 3% and water potential 15 kPa or greater. Coiling began at a much lower water pote...
متن کاملUltrastructure of the spicules of Pratylenchus penetrans.
The two spicules of PratyIenchus penetrans are not morphologically identical. The outer spicule is slightly larger and longer than the inner spicule. Each spicule is composed of a blade, shaft, and base. The spicules originate from the gradual thickening and invagination of the posterior walls of the spicular pouch. At the tip of each spicule are two small pores with one dendritic process assoc...
